Case study, Nutella supposedly is made up of:
Low carb alternative could be:
|low carb chocolate
|allulose or erythritol (maybe a little stevia to taste)
|dry or oil-based vanilla flavor, pinch vanillin
You can not add any water or alcohol based liquids (like vanilla extract) to this or it will seize!
I normally lightly roast the hazelnuts to dry out any water and bring out the flavor.
A malanger is a must to grind down everything. Make sure all the ingredients are in a molten form if possible.
